The 27-year-old native Californian will be a presenter at the official Neighborhood Ball according to the Presidential Inaugural Committee. Other presenters include: Denzel Washington, Leonardo DiCaprio, Ray Romano, Jamie Foxx, Queen Latifah and Kate Walsh.

Last weekend, the Fantastic actress threw a surprise party for husband Cash Warren‘s 30th birthday in Vegas. She reportedly got 80 of her husband’s closest family and friends for the celebration! “I would be remiss if I didn’t thank my beautiful wife and best friend in the whole world, Jessica,” said Warren. “I can’t tell you how surprised and happy I was to see all of you. Those tears were real. I can’t act. It doesn’t run in the family. But it’s tears of love for all of you. I was so surprised and happy to see all of you!”
